Analysis of the Physical Fitness Level of Students at SMP Jalan Jawa Surabaya

Abstract

This study aims to analyze the level of physical fitness among students at SMP Jalan Jawa in Surabaya using the Nusantara Student Fitness Test (TKPN). This study employs a quantitative approach with a descriptive design. The population consisted of 122 students, all included through total sampling. Data were collected using TKPN components: BMI, flexibility, muscle strength and endurance, and cardiorespiratory endurance. Data were analyzed using descriptive statistics, namely frequencies and percentages. Results showed overall fitness was in the poor category 92.6%, while 7.4% were adequate, with none good or very good. For BMI, most students were overweight, boys 50.00% and girls 64.29%. In flexibility, females were mostly excellent 72.73%, while males were adequate 32.14%. In muscle strength and endurance, most students were poor or very poor, boys 81.82% and girls 76.79%. In squat thrust, most were adequate to very good. Cardiorespiratory endurance PACER showed the lowest results, dominated by very poor, boys 98.48% and girls 83.93%. These findings indicate that low fitness is mainly influenced by weak cardiorespiratory endurance and muscle strength. Therefore, improvements are needed through optimizing PJOK learning, implementing structured exercise programs, and promoting active healthy lifestyles at school and home environments. These interventions should be consistent, monitored, and supported by teachers and parents to ensure sustainable improvements in students’ physical fitness levels and overall health outcomes in adolescence and future development stages across different school contexts and demographic backgrounds for broader applicability.
